Add Privacy Compliance Scanning to Claude Code
The article explains how to embed privacy-compliance checks into Anthropic's Claude Code workflow by adding a CLAUDE.md rule that flags privacy-relevant dependency additions (analytics, advertising, payments, auth, error tracking, session replay, email, push). When such dependencies appear, Claude Code can notify developers about typical personal data collected, suggest running PageGuard (npx pageguard) for a full scan, and note likely requirements (privacy policy, cookie consent, DPA). The post also describes installing the PageGuard CLI (npx pageguard --init) and pairing CLAUDE.md rules with a PageGuard GitHub Action (AuxiliumApps/pageguard-action@v1) to catch issues in pull requests.
Embeds privacy and consent checks into LLM-assisted developer workflows and CI, reducing compliance risk for projects that add analytics, advertising, payments or tracking SDKs — relevant to AdTech/MarTech but not industry-shifting.

Key Takeaways & Evidence Grounding
- CLAUDE.md is a persistent memory file that Claude Code reads at the start of every session and can contain rules.
- The provided CLAUDE.md rule instructs Claude Code to check dependency files (package.json, requirements.txt, go.mod, pubspec.yaml, Gemfile) for packages that collect user data across categories like analytics, advertising, payments, auth, error tracking, session replay, email, and push.
- The rule recommends suggesting a compliance scan using the PageGuard CLI (npx pageguard) and notes typical compliance steps (privacy policy, cookie consent, Data Processing Agreement).
- The article shows integrating PageGuard into CI with a GitHub Action: AuxiliumApps/pageguard-action@v1 to run scans on pull requests and catch compliance gaps.

PageGuard Cursor Rule Adds Privacy Compliance Nudges
PageGuard published a Cursor IDE rule (pageguard.mdc) that detects privacy-relevant dependency changes and provides in-context compliance guidance to developers. Installed in .cursor/rules/, the rule flags additions of analytics, advertising, payment, authentication, error-tracking, session-recording, email and push SDKs, explains typical personal data collected, and suggests running the PageGuard CLI (npx pageguard) for a full scan. The PageGuard scan returns six scores (Privacy Risk Score, Security Headers, Accessibility, Performance, AI Readiness, Structured Data). The rule can be installed manually or downloaded from the PageGuard GitHub, and PageGuard's CLI works across editors (Cursor, Claude Code, any terminal). Scan results are free; PageGuard offers paid document-generation features for tailored privacy policies and remediation guidance.
Ten CLAUDE.md Rules for Safe Claude Code
Rene Zander published a developer post (Apr 23, 2026) that collects and extends CLAUDE.md guidance for using Claude to write and run code. He preserves Forrestchang’s four edit-time rules (Think Before Coding; Simplicity First; Surgical Changes; Goal-Driven Execution) and adds six runtime rules derived from his fixclaw project: prefer deterministic code for operational tasks, declare token budgets and halt on breaches, treat human-in-the-loop approval steps as first-class, validate AI outputs against schemas, sanitize operator input to prevent prompt injection, and log rejections silently. The article links to a GitHub gist and describes fixclaw (a Go pipeline engine) as an implementation where Claude drafts and classifies but never executes side-effecting actions. Sentry monitoring is mentioned as a practical observability option.
Claude Code Guardrails: Context Bleed and Acceptance Blindness
A 2026 DEV post warns that widespread production use of Claude Code has exposed gaps in how teams build guardrails and maintain code comprehension. Drawing on a Qiita post by nogataka, the article describes a repository-level guardrail architecture (configs, policies, hooks) used by Japanese enterprise teams to enforce context isolation and secret scanning. It highlights a distinct operational risk — “context pollution” (文脈汚染) — where shared model context can leak between projects, and describes “Acceptance Blindness,” a tendency for developers to accept AI-generated changes without sufficient review. Recommended practices include explicit 'no AI zones', comprehension-verification workflows, quarterly guardrail testing, and tracking acceptance-to-understanding ratios. The piece also flags upcoming risks as Claude Code moves to background/streaming executions in IDEs (v2.x).
